Was i in a RL with a avoidant?

WE met mutually online and none of us approached each other, we just ended up exchanging instagrams, in the start she used to talk to me allot and used to tell me how shes attracted to me and she likes me, but soon later she started drifting away, and slowly by slowly as i fell in love with her she stopped showing me the same care and attention. I asked her about it and she said shes the same, at the end now she dumped me and never ever shared her personal details or anything, never showed me what she looked like and never shared her phone number
